Yup.

I never used SO_LINGER before.
From the description in `man 7 socket`, active SO_LINGER just makes shutdown() to block if not all data has been transmitted (and ACKed?). close() on a socket calls shutdown() automatically (unless the shutdown() has been already called).
The timeout which you're application runs into applies after shutting down/closing the connection.
